Likely nothing as astonishing as Aron Hodek. According to his Instagram account (aronthebassist), this child from Slovakia loves watching Tiny Desk videos and playing along with them. Here, he accompanies Mac Miller's Tiny Desk concert — and, in particular, Thundercat's bass line (look out Thundercat) in "What's the Use?" Aron's cadence and groove were pretty damn remarkable and put a huge smile on my face.
